Abstract
A rotational intravascular ultrasound probe for insertion into a vasculature and a method of manufacturing the same. The rotational intravascular ultrasound probe comprises an elongate catheter having a flexible body and an elongate transducer shaft disposed within the flexible body. The transducer shaft comprises a proximal end portion, a distal end portion, a drive shaft extending from the proximal end portion to the distal end portion, an ultrasonic transducer disposed near the distal end portion for obtaining a circumferential image through rotation, and a transducer housing molded to the drive shaft and the ultrasonic transducer.
Claims19
A rotational intravascular ultrasound probe for insertion into a vasculature, the probe comprising:
- an elongate catheter comprising a flexible body;
- and
- an elongate transducer shaft disposed within the flexible body, the transducer shaft comprising:
- a longitudinal axis;
- a proximal end portion and a distal end portion;
- a drive cable extending from the proximal end portion to the distal end portion of the elongate transducer shaft, the drive cable comprising a distal portion;
- an ultrasonic transducer for obtaining a circumferential image through rotation, the ultrasonic transducer disposed at the distal end portion, wherein the ultrasonic transducer comprises a stack of layers extending perpendicular to the longitudinal axis;
- a plurality of electrical wires passing through the drive cable to the ultrasonic transducer;
- and
- a transducer housing conforming to and physically contacting the distal portion of the drive cable, one or more layers of the stack of layers of the ultrasonic transducer, and the plurality of electrical wires.
